SELMA, Ala. -- Sen. Hank Sanders, D-Selma, has written an open letter to U.S. Rep. Artur Davis, saying he is concerned about the congressman's plan to vote against legislation to overhaul the country's health care system.

Sanders' letter was sent on Friday, two days before Sunday's landmark vote.

Davis, a Democrat from Birmingham and 2010 gubernatorial candiate, has said he has several concerns about the 10-year, $940 billion measure, including its cost.

Sanders said he knows the bill isn't perfect but said as a senator if he waited for perfect legislation before voting yes, he'd never vote.

"We have to get as much as we can and then stand strong," he wrote.

Rep. Bobby Bright, D-Montgomery, has also said he plans to vote against the legislation, citing the "massive cost."
